Wow I can't believe This statement
" You guys don't need to have a soundcheck anymore. Younow have in-ear monitors so there is no need" 
So last night I was in the car with out Head A/V person and asked if he could be at church a little early this morning...(it's 6:30am here now)? We just got a new in-ear monitoring systems for each musician and vocalist and we are not yet accustomed to the system and we need to have a longer sound check. His exact response was " You guys don't need it, you have your own in-ear monitors."

At this point I try to expalin to him the need for a sound check if for no other reason that, it's new system ( 1 week -old) and things can happen and we want to be aware of any possible issue before service actually begins so that we can be sure to have enough time to trouble shoot and put out any fires. This escalated into a very heated argument about the A/V departments on going issues.
However... it became an issue because The sound man actually said " You guys dont need to have a sound check.
Is there ever a time in any event; church service, concerts etc... that you don't need some sort of sound check?
And has anyone ever heard a sound man say " you don't need to have a soundcheck?"
I may be wrong so I need honest feedback and or "experienced" people in sound to respond.
I appreciate it because I have to address this in 4 hours.
